What is a Mini Documentary? Many say they are short films and they would be correct. A mini documentary is a way to explore and get a message across. I have used this method of film making when I created a fundraiser film for Mighty Moms Foundation. You are able to pack in a lot of info in a short amount of time. Many of my mini documentaries are in the 4-6 minute zone. I in particular really like mini docs because you are able to focus on a subject for only a short amount of time. Let’s face it, we as viewers have a very short attention span. Check out my mini documentary on Dusty Buns.
